Join Mountains Restoration Trust to preserve and protect the streams and creeks of the Malibu Creek Watershed. The invasive, non-native crayfish are harmful to the ecosystem of the Santa Monica Mountains. They prey on native species, reduce water quality, and cause problems with creek bed erosion. We need your help in trapping and removing the crayfish as well as picking up trash along the stream.
Great Fun for Kids and Families! Volunteers 16 years or younger must be accompanied by a parent or guardian. Volunteers under the age of 18, must bring state-parent-waiver with a parent or guardian’s signature if the parent or guardian is not attending.
Registration is Required: Registered volunteers will receive an email confirmation with more details.

- Red Swamp Crayfish are native to the South Eastern United States and Northern Mexico
- They are a freshwater crustacean
- They can reach 12cm (~ 5 inches) in length
- They will feed on anything from plant debris to larvae, tadpoles, and snails
Crayfish are detrimental to the ecosystem of the Santa Monica Mountains because they:
- Prey on native species which drive native populations down, such as the Arroyo Chub, California Newt, California Tree Frog, Baja California Tree Frog, and the Southern California Steelhead Trout.
- Burrow which causes problems with water quality and creek bed erosion
- Feed on native plants which cause reduction in plant biodiversity and quantity
- Can serve as a primary food source for other invasive species such as the largemouth bass, catfish and bluegill
